MP2 (t1395)
CO (t5580)
Hero (Button) (t1165)
SB (t2665)
BB (t3305)
UTG (t5150)
UTG+1 (t3425)
MP1 (t1170)

Hero's M: 3.88

Preflop: Hero is Button with 10, 10
2 folds, MP1 bets t400, MP2 raises to t1395 (All-In), 1 fold, Hero calls t1165 (All-In), 2 folds, MP1 calls t770 (All-In)

Both are aggressive laggs and this is an easy call. I would suspect MP2's range to be ace heavy so like AJ+ 88+ but also like KJ, KQ hands. MP1 is doing this with a ton.
