Learn Dutch: Zullen wij gelijkspelen? Ik denk van wel, ik kan dat goed inschatten. - Will we tie? I think so, I can estimate that well.

Both Ik denk van wel and Ik denk het wel translate to "I think so" and are very natural in Dutch. Using van wel (and van niet for "I don't think so") is a common way to substitute an entire clause after verbs of thought or communication. Here, it stands in for "I think that we will tie".

Is gelijkspelen a separable verb?

Yes, it is a separable verb made of gelijk (equal/even) and spelen (to play). Because the auxiliary verb zullen (will) is used here, the main verb gelijkspelen is pushed to the end of the clause and written as one word. In a normal present-tense main clause, it splits: Wij spelen vaak gelijk (We often tie).

Could I use het instead of dat in ik kan dat goed inschatten?

Yes, you could completely naturally say ik kan het goed inschatten. Using dat simply adds a bit more emphasis, pointing directly back to the idea of tying: "I can estimate that well" rather than "I can estimate it well".
