Borgata 10k HELLLP

[mastr]

I've asked tons of people this and everyone is split exactly 50/50 so far on what to do this hand, gimme the advice guys...
200/500/50 i have 24-26k I think around 25, was at 4k at start of level have been opening a good amount of pots..
10 handed table,

we're in mp3 and make it 1500 with AKo

Cutoff = old nit, but not terrible at all at poker. He says he plays online every day and I'd assume him to actually be around a breakeven player, slightly minus, but def not like most old nits.
Cutoff 3-bets to 5k... this is either his first or 2nd 3bet in the 8 hours we've played together, his stack is 45k

Small Blind = Ted Forrest, he's been opening a ton of pots, and winning with c-bets on flops and turns fairly easily, hasn't been 3betting a ton, and has 65k in the stack

Small blind thinks for maybe 25 seconds then coldcalls...

Action on us, 13k in the middle....
