Floating in Poker: An Example

$0.50/$1.00 home game

Hero covers all.

Towards the end of the night and we’re playing 5 handed.

I open   UTG to $3.

V3 calls OTB, FISH calls from SB, TAG calls from the BB.

FISH bets 2.50 (lol). TAG raises to $5.

…

I am 100% sure FISH will call the raise for 2.50 more, So right now I have to call 5 to win 22, perhaps 27 if V3 comes along also. I call. V3 folds. V2 calls.

Wondering if this call is ok.
