player A: summons 1500+ atk monster
player B: responds by activating bottomless traphole
player A: chains with book of moon

when it resolves, will the monster stay on the field or will it be removed??

Bottomless Trap Hole requires a face up monster upon activation and resolution, so by playing Book of Moon you will have 'saved' your monster.

Here are the netrep rulings

This card can remove from play multiple monsters at once, if they are Summoned simultaneously. Since this card can affect multiple monsters, it does not target.


If the opponent has "Lord of D." on the field and activates "The Flute of Summoning Dragon" to Special Summon 2 copies of "Blue-Eyes White Dragon", you can activate this card and both will be removed from play. "Lord of D." does not protect the Dragons because "Bottomless Trap Hole" does not target. The same situation would occur if only 1 "Blue-Eyes White Dragon" was Special Summoned, "Bottomless Trap Hole" still does not target.


This card can only be activated when the last thing that resolved in the Duel was the opponent Normal/Flip/Special Summoning a monster(s). It cannot be activated at any other time.


If "Cyber Jar" is flipped during a Main Phase, and the opponent Special Summons "Dark Blade", "Luster Dragon", "Magical Scientist" and a face-down monster, you can activate "Bottomless Trap Hole" and both "Luster Dragon" and "Dark Blade" will be removed from play. The "Magical Scientist", face-down monster, and all monsters you Summoned will remain on the field.


If "Cyber Jar" is flipped as a result of being attacked, you cannot activate "Bottomless Trap Hole" because it cannot be activated during the Damage Step.


If the opponent Summons a monster, then you activate "Bottomless Trap Hole", and the opponent chains "Book of Moon" to flip the Summoned monster face-down, it is not removed from play by the effect of "Bottomless Trap Hole".


Use the current ATK at time of Summoning to determine if you can activate "Bottomless Trap Hole". So if the opponent Tribute Summons "Enraged Muka Muka" with 1 card in their hand, you can activate "Bottomless Trap Hole" (since its ATK is 1600).


You cannot activate this card after "Jinzo" is Summoned.


You can activate this card after a monster was Special Summoned by the effect of another card, such as "Monster Reborn".


If the opponent activates "Monster Reborn" and then chains "Call of the Haunted" (so that 2 monsters are Summoned in the same chain), and then you activate "Bottomless Trap Hole" after that chain resolves only the monster Summoned by chain link 1 ("Monster Reborn") is removed from play.


If the opponent Normal Summons "Dark Blade", then you activate "Bottomless Trap Hole", and the opponent chains "Ultimate Offering" and Tributes "Dark Blade" to Tribute Summon "Summoned Skull", the chain will resolve like this. "Dark Blade" is sent to the Graveyard and "Summoned Skull" is successfully Summoned, then "Bottomless Trap Hole" resolves and removes "Summoned Skull" from play.

would it resolve the same if my opponent used sakaratsu armor when he attacked and i chained with book of moon??

The same ruliong applies.

Book of Moon will save your monsters from being destroyed by Sakuretsu Armor.
