Stupid Raise or Did I Save a Bet?

[Mr. Curious]

It seems like you were looking for a fancy way to lay this hand down.

You 3-bet the turn and fold to a raise, which costs you the pot if you are ahead and saves you two theoretical bets if you are behind (calling and then c/c the river).

If you had instead just called the turn raise and check/called the river, it costs you the same amount as the 3-bet, but gives you a chance to still win the pot if MP is a donk, plus you get some info about how MP plays. This is especially important in relation to how the hand played given MP's 2 cold calls preflop and 2 more cold calls on the flop.

btw - I take it niether of your cards were a spade?
